The incident happened just before 10:30 p.m. at the Gulf Mart on Congress Street.

Eddie Ahmed, the clerk and owner of the store, said a man walked into the store and showed a handgun while demanding cash.

"I was just sitting down, minding my own business and I had to get up and actually give him something that he doesn't really deserve," Ahmed said. It doesn't happen everyday that someone comes in trying to do this. I was calm, collected and I actually tried to yank his gun out of the way. He got scared. Typical."

Images from surveillance video show the robber pointing a gun at the clerk.

However, police said the man left the store without any money.

"As I was chasing him back I was yelling at him," Ahmed said. "Using words I can't say right now. He ran away like a little girl."

No one else was in the store and no one was injured, police said.

Anyone with information about the attempted robbery is asked to call Portland police.
